Abstract: Abstract A dispenser system for dispensing a plurality of twist-ties like closure devices 52 arranged in side-by-side alignment and attached at a second end 61 in sheets 50. The attached second ends 61 are crimped about a rod 51 which is inserted in slots 107 defined in side edges 102 of dispenser 100.  A plurality of sheets 50 may selectively be inserted in dispenser 100.  The dispenser also includes a cover 103 and a tie alignment block 106.  The individual ties have a series of transverse perforations 53, 54 through the wire 55 and proximate the wire 55 to ensure ease of removal and ensure reference of the steel rule die 250 utilized in fabricating the tie 52.  Fabrication of the sheets 50 includes taking a stock of uncut twist-tie material 201, advancing it into a cutting station 203 utilizing a steel rule die 250.  Advancing the material repeating the cutting step which forms the second end 61 of the advanced sheet and then advancing the cut sheet 50 to a crimping station 205.

Abstract: The invention relates to a device for the reintroduction of solid developer particles, which have been separated from a gaseous carrier flow, into a reservoir that is open to the air. The derive (60) is disposed between the reservoir (15) and the apparatus (26) for separation and recovery of particles, and it includes a chute (61) into which the discharge conduit (47) of the apparatus discharges. A transport element (65) that slides inside the chute (61) isolates the discharge conduit from ambient atmospheric pressure. This transport element is provided with a cavity (67) in which the particles that drop into the conduit accumulate, and the accumulated particles are then transported outside the chute and drop into the reservoir (15). The invention is applicable to non-impact printing machines.

Abstract: ABSTRACT A pipelined error correction circuit iteratively determines syndromes, error locator and evaluator equations, and error locations and associated error values for received Reed-Solomon code words.  The circuit includes a plurality of Galois Field multiplying circuits which use a minimum number of circuit element to generate first and second products.  Each Galois Field multiplying circuit includes a first GF multiplier which multiplies one of two input signals in each of two time intervals by a first value to produce a first product.  The circuit includes a second GF multiplier which further multiplies one of the  first products by a second value to generate a second product.  The first and second products are then applied to the first GF multiplier as next input signals.  The multiplying circuit minimizes the elements required to generate two products by using a first, relatively complex multiplier for both the first and second products and then a second relatively simply multiplier to generate the second product.  This simplifies the multiplying circuit which would otherwise require two relatively complex multipliers.  The error correction circuit determines, for each received code word, an error locator equation by iteratively updating a preliminary error locator equation.  The circuit determines for a given iteration whether or not to update the preliminary error locator equation by comparing a particular variable with zero.

Title: Air bag in air bag equipment
Inventor: TAKAMIYA TOSHIO
IPC: B60R21/264
Filed: 1990-07-16
Granted: 1997-11-18
Abstract: The air bag 3 according to this invention is furnished with exhaust outlet 6 to discharge internal gas, and the material 8 with heat-shrinking property is provided, which blocks at least a part of the exhaust outlet 6 in normal case and shrinks to such direction as to increase the passage area of said exhaust outlet when reaction gas is introduced from the inflator 2.    Therefore, the passage area of the exhaust outlet 6 is relatively narrowed down by the heat-shrinking material 8 in normal case.  For this reason, it is rapidly expanded by reaction gas from the inflator 2.          Thereafter, the material 8 is shrinked by the heat of reaction gas and the passage area of exhaust outlet 6 is increased.  Thus, more reaction gas flows out of air bag 3, and this alleviates the impact when the air bag 3 receives the person in the vehicle.          In this case, the shrinking degree of the material 8 varies according to the ambient temperature, and the internal pressure of the air bag 3 is maintained at almost constant level regardless of atmospheric temperature.  As the result, the air bag 3 can receive the person in the vehicle always in stable condition.
